T 0 all whom 'it may vconcer-n.'

Be it known that I, STANLEY W. HAYES, United States citizen, residing inRichmond, county of Wayne, Indiana, have invented the followingdescribed Improvements in Derails. Y Y i The invention provides a lightweight derail that can be conveniently thrown either by hand orpipe-line and consists in the structure of the derailing member and itsrelation Yto theguide box or base and in the organization therein of ahand operated power-'multiplying mechanism as hereinafter ,explainedandmore particularly pointed out in'the claims. VIn the drawings- Fig. 1is a side elevation of the derail on the .rail. A l A Fig. 2 'is apartly sectional elevation of 'the same derail partly Withdrawn.

` Fig. 3 is a side elevation of the rail,

Fig. 5 a rear View partly in section showing the rear bearing.'

The base member comprisestwo upstanding side wall portions 1, united bylower cross wall portions 2 and 3 the latter provided with exteriorspike flanges i adapted to be spikedto two adjacent ties. rl`he base isopen, having no uppercrossbar or roof member, and the interioris'occupied by the derailing member, which latter is mounted on forwardand rear bearings therein so that itV advances horizontallyv to the railand withdraws therefrom,'iirst,with an upward and then with a downwardmovement, its withdrawn or open position being depressed at oneoside ofthe rail. The derailing mem ber comprises the body or supporting part5and the derail block 6 and is cast in one piece and hollow on its underside for lightness and to provide accommodation and shelter to the rearbearing and subjacent parts. The forward bearing is provided by twostuds 7 projecting laterally from the .lower end of the shoulderstructure 8 at the forward end of the body part of the derailing member,near the derail block2 and sliding fn, grooves 9 formed in the innerfaces "of the sides 1. rllhese grooves are curved to give the derailblock the up-andover movement above mentioned and their engagement withthe studs also serves to hold Ithe derailing member against upwarddisplacement. This particular lform of forbase lug 12 and von the other,by the undercut base lug 13, the structure of which overlaps a side rail14 on the rib 10 to keep it 'from upward displacement.v Such rear'ribbearing is central between the vertical planes of the'two forwardbearingstuds i7, and thereby prevents cram-ping of the member inthe'base, while the vertical curvature of the rib contributes adesirableV additional vertical component to the motion ofthelderailingmember, designed te keep the operating lug 15, and hence thepipe-line rod 16 attached thereto, at a substantially conf stantlevel inall positions, and otherwise to facilitate the movement of the member aswill b e apparent, The saidoperating lug 15 is cast on the rear of thebody 5, and eX- tends downwardly to a point below the level of the crosswalls 2 and 3 so that the pipeline when used, may run as usual beneaththe rail. The derail' shown may also be provided with a duplicateattachment lug 17 (Figs. 4L` and 5) 'for connection to a target staff orother track appliance or connection as desired.

For d'rect hand operation, theV derail is provided with a power-multipledevice in the form of a hand lever 18 fulcrumed on a lower stationarysupport, for instance upon the lug 19 projecting from the forward sideof the cross wall 3 and having a bearing on the derailing memberpreferably at a central point thereof and by means of this lever 'theheaviest sizes of derails may be thrown with little effort.I Thepreferred form of operating mechanism is a' lever of the second class asshown, passing through a hole 20, in the forward center of the body 5,and curved in a fore and aft direction so that it can occupy asubstantially horizontal position when the derail is off the rail.Derails are commonly placed between the rails of the track and the lever18 is therefore in this manner arranged to be out of the way of passingrolling' stock when the derail is open, .while when the derail is closedthe hand lever is upstanding and may serve as a signal device dependingon its length. The curvature of the lever is preferably formed in thatpart of its length which engages the bearing represented by the roundededges of the hole 20, and thereby it acts with a camming effect on thederailing member, further multiplying the power effect thereon which isparticularly useful in raising it'from its depressed position againstobstruction by .frost or other cause. Such camming effect issupplementary to the primary function of the-'lever and due to itscurvature but the invention contemplates the use of anypower-multiplying mechanism as a means of enabling largesized and heavyderails to be directly thrown by hand by an operator standing at thederail. Such mechanism may however be omitted when the derail is to beoperated solely by the pipe-line, but the structure is preferablymanufactured with the fulcrum lug 19 and with the other lugs l5 and 17upon it in any case, so that itV may be sold for use either way.

The two mainv parts of the derail are assembled by placing the derailingmember in the bas'ein a` position slightly forward of that indicated inFig. l, and before the base is spiked to the ties and then introducingvthe rib 10 and studs 7 into their yrespective bearings and sliding themrearwardly therein. When the base is thereafter secured to the ties theobstruction represented by the adjacent rail-head confines the derailingmember in its bearings vas will be obvious.v The rear end of the sidewall portion is provided with a perforated' ear 23 and the derailingmember is formed with two abutment surfaces 2l and 22 so that a padlockhasp inserted through the ear will coact with either abutment to lockthe member either opened or closed.

It should be noted that the studs 7 are located at the eXtreme forwardend of the base and are therefore close to the rail when the derail isopen, in which position their function of holding the block againstkicking up on wheel impacts is most eective, being thereby freed frommuch of the leverage effect that has heretofore been present in derailshaving the sliding movement above described. This result is obtained byforming the said studs 7 at the lower ends of the shoulder structure 8directly under the derail block 6 instead of on the sides of the bodypart 5 of the derailing member,

Vvand it i's manifestly independent of the 60v specific manner ofvsliding support.
